Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. An improved cap retaining means for containers having a neck portion through which the contents of the container may be discharged and a cap cooperating with the neck portion, said neck and cap being screw-threaded and the cap having an external annular groove, and the container having an external lug, comprising a resilient retaining wire looped to provide a bight disposed in the cap groove and encircling and freely journailing the cap, and having ends disposed in holes of the lug, there being two separate holes, with the axis of each being out of line with the axis of the other, the ofiset alignment of the holes with the ends of the wire therein functioning to move the member-and the cap carried thereby with a spring action in opening or closing movement.

2. The combination of a container neck having external threads, an internally threaded cap therefor, a looped wire link having a bight encircling the cap and freely journalling it therein, a lug on the container provided with two separate and distinct out-of-line holes, the two ends of the link being bent towards each other and being disposed separately in said holes.

3. A combination of the character described in claim 1 where the lengths of the wire halves from neck to hole are unequal.

4. A combination of the character described in claim 2 where the lengths of the wire halves from 20
